论文摘要
提出了对$ b \至d^*（dπ）\ ellν_\ ell $衰减的无键角度分析的灵敏度研究。在分析中，结果表明，右撇子矢量电流的Wilson系数$ c_ {v_r} $可以使用完整的正常的Angular可观测值或10 $ W $ w $ w $ w $ w $ w $ w $ w $ w $ w $ w $ w $ w $ w $ a_ {fb a_ {fb a_ {fb a_ {fb} $的精确度为2-4 $ \％$。这样的角度测量与$ v_ {cb} $拼图无关。
A sensitivity study of the unbinned angular analysis of the $B\to D^*(Dπ)\ell ν_\ell$ decay is presented. In the analysis, it is shown that the Wilson coefficient of the right-handed vector current, $C_{V_R}$, can be measured to precision of 2-4$\%$ using either the full set of normalised angular observables or the forward-backward asymmetry $A_{FB}$ of the charged lepton in 10 $w$ bins. Such angular measurements are independent of the $V_{cb}$ puzzle.
